The Bongar Family has always been involved with environmental concerns of the country started by their patriarch Engr. I.M. Bongar, who was sent by his Employer to train in the U.S. in 1967 for the Design and Construction of Sewage Treatment Plants.

In 1978, Engr. I.M. Bongar established I.B. ENGINEERING, his own proprietorship which built its first STP contract for Texas Instruments in Baguio City. In 1991, it became a family corporation and did not only constructed buildings and waste waster treatment plants but also solid waste composting and recycling.

After years of service, Engr. I.M. Bongar and son, also an Engineer, together established a Company, Bongar Envirosystems Technologies Co., formed as a Partnership between father and son in November 3, 2004. On September 28, 2009, the partnership was dissolved and converted to a closed family corporation under the name BONGAR ENVIROSYSTEMS TECHNOLOGIES CORP., with all the other siblings involved in the business.

To date we have undertaken several sewage treatment plants under I.M. BONGAR & CO., INC. and BONGAR ENVIROSYSTEMS TECHNOLOGIES CORP. Eventually, the latter company will inherit all environmental business concerns as the former will focus on general engineering and building construction and the latter on waste water treatment plants, solid waste composting and recycling, and structural steel fabrication and construction.
To date, this family’s corporation counts on several premier corporations of the country such as AYALA CORP. and DMCI HOMES, INC. and the VILLAR conglomerate as its major clients for waste water treatment plants and several LGU’s all over the country for its accelerated composting machines and plastic recycling machinery.

The bright future of this Corporation rely on the issue of Global Climate Change and the Government’s strict implementation of Republic Act 9275, The Clean Water Act; Ecological Solid Waste Act of 2000; and Philippine Clear Air Act of 1999.
